resident of Ovid, inthe county of Seneca, in the `State of New York, have invented new clear, and exact description:`

This invention relates to certain improve .w ments in vehicle wheels of the yielding riin type adapted to afford suficientresiliency to tahe the place of the usual pneumatic tire, and at `the saine time providingsuitable clenclier rings for the reception and retenf` tion ot a Hexible tread of rubberi,1leatherr other suitable material. p

@ne 0l the objects is tol provide a vehicle wheel oi" this character in which the tire may closely resemble the ordinarypneuniatic tire without the use `of any pneumatictubes or compartments, at `the same time maintaining a degree of resiliency suliicientto prevent` i the transmission of vibrations to the felly in passing over uneven road surfaces: 1i

Another object is to provide tlievvlieel` with comparatively lightinternal andleirter` hal. rims' and interposed sprin`g-disteiided piangere supporting the outer rim and tele scoping `with sockets in the inner rim to atl'ord the necessary resiliency, and atthe-w same time `to guide the rims in their relat tive radial movement throughout their cir-` cumlferential lengths.

er further object is to provide the` outer riin with removable elencher rings.t`or`re'-` ceiving and retaining a tread or shoe thereon, and also to utilize portions of the eleiicher rings to coperatie with the inneri rim in holding the outeri'ini and its slice or tread in the same plane of rotation` asisthef.n

telly and inner rim. p

A. still further object is to divide the outer rini and its clencher rings and shoe through dianietrieally opposite sides and to connect their adjacent ends by locking members, the

other of which may constitute a hinge to Other objects andiuses relating to specific l parts of the wheel will be brought out in the and useful Improvements inYehiele-Vilieels,\` ot which the following, taken in connection 'with the accompanying drawings, isa full, i

clencher :rings is broken away.

Fig.: `2 is an enlarged longitudinal sec. f tionalztview of a portion of the telly, inner `rim and tire showing one of the plungers in elevation and the other in section.

Figq is an `enlarged transverse sectional view through thefelly, rim and tire taken on line 3-3, Fig. 1. v

As-i1lustrated,.tliis wheel comprises a hub 1 having radial spokes J2- connected `at their outer ends to a felly .W3- upon `which is mounted aii inner rim -4 v The rim -4- is provided with a series of radial socketsf-n in uniformly spaced relation eii'euinfereiitiallyfor receiving a corresponding number of radial plungers G `which are spring pressed outwardly by coil springs @7e andare provided with circumferentially elongated outer ends or heads -6-'-- are cylindrical andhollow and tele` scope withinthe sockets the springs -7`-=havingtheir inner ends seated in their respective sockets, and their t outer ends seated in the corresponding sockets in the cylindrical portions of the plungers and are,

therefore, protected from external elements. The innerrim lis also provided with hollow bosses -10- projecting radially and centrally into the sockets 5 for receiving nut pistons l1- nwhich are engaged by screw rods `-12-- passedoutwardly through reduced openingsin the outer ends of the bosses :--l0-. and attached to the heads f m8#- of the plungers -6- to not only ad- -llin their respective bosses -10-, but also to limit both the inward and outward movement of both rims relatively to each other.

The screws -12- and their nuts -11- also permit the corresponding portions of the rims to be adjusted radially to bring them into exact concentricity, it being understood that the springs -7- are. tensioned to a sufficient degree to force the adjacent portions o the rims apart to the limit of their separating movements, as determined by the engagement of the ,nuts

-1lwith the outer ends of the bosses 10 under normal or light load.

The outer ends of the plungers -6- are provided with opposite outwardly projecting flanges 13 in spaced relation to receive the adjacent portion of the outer rim -9- between them andto assist in holding said outer rim against lateral displacement from the heads 9- of the plunger -6-, as shown more clearly in F ig. 3.

The outer rim -9-- is preferably T- shape in cross section and arranged with its reduced portionbetween the flanges -13- and the opposite sides of its opposite wider portions overhanging said flanges in radially spaced relation thereto so as to allow a limited radial movement of both the inner and outer rims relatively to each other.

rl`he periphery of the rim --9- is substantially flat transversely for receiving and ksupporting a flexible tread or shoe 11iof rubber, leather or equivalent material which is also substantially T-shape in cross section, the inner side thereof being of substantially the same width as that `of the periphery of the rim -9-.

T he opposite edges of the tread or shoe -14- are provide-d with V-shape annular grooves'v for receiving the adjacent outer edges of a pair of oppositely disposed clencher rings l5- which are clamped to the opposite sides of the outer rim --9-- by bolts -16-, as shown more clearly in Fig. said bolts being passed through registering apertures in the rings and outer rim.

T he outer rim -9- and its clencher rings -15- together with the tread or shoe -l4-, constitute the tire, all of said parts being divided at -17- and -18- through diametrically opposite sides to permit the tire to be placed over and upon the outer ends of the plungers -6- between the flanges -13-, after which their meeting ends are firmly connected together by tiepieces -19- having apertures for receiving the adjacent bolts -16- which are seated in grooves or slots 20- of substantially the same size as the tie-pieces and it, therefore follows that if one of the bolts 16- at each side of the tire is removed, the half sections may be separated, or if one of the bolts is removed at one side, the sections may be rocked about the axes of the bolts at the opposite side, either of which operations may be employed in placing the tire upon the outer ends of the plungers, said bolts also serving to permit the removal of either one of the clencher rings in placing the shoe or tread 14- upon or removing it from the outer rim.

The hub, spokes and telly may be of any 'desired construction, the inner rim --4:- being fitted tightly upon the periphery of the elly and secured thereto by any suitable fastening means not necessary to herein illustrate or describe.

The springs -7- are then placed over and upon the bosses -1()-- within the sockets -5- and secured in place by the bolts l2- and nuts 1lwhich are adjusted to bring the heads of the plungers -Gw into concentricity with the inner rim l-, after which the tire sections including the inner rim -9- may be placed over and upon the outer ends of the plungers between the flanges -13- and properly 'lastened together by the tie-pieces -l9-, whereupon the wheel is ready for use.

that l claim is:

1. In a vehicle wheel, the combination of an inner rim and a series of radial plungers spaced uniform distances apart circumferentially relatively to the inner rim, said rim and plungers having telescoping parts, coil springs between the rim and plungers and normally tensioned to force the latter outwardly, said rim and plungers having coperative means for limiting their relative radial movement, and an outer rim seated upon the outer ends of the plungers.

2. In a vehicle wheel, the combination of an inner rim and a series of radial plungers spaced uniform distances apart circumferentially relatively to the inner rim, said rim and plungers having telescoping parts, coil springs between the rim and plungers and normally tensioned to force the latter out- -wardly, said rim and plungers having cooperative means for limiting their relative radial movement, an outer rim seated upon the outer ends of the plungers, said outer rim being divided through diametrically opposite sides, and means for locking the adjacent ends ot the opposite half sections of the rim to each other.
